Reactor slow to respond to emergency

Thousands of Flatworms are killing my tank. Should I turn the Carbon Reactor back on?

Answer:  Okay yes, but it won't help fast enough. Instead, lay or hang a loose bag or two of AC right over or next to the main circulation/return pump. Replace the bag(s) with new AC every hour or two for the first 4 hours. This removes the toxins and the dosed chemical. Whether FWExit or pure Lavamisole, the chemical is relatively harmless to other animals, but if left in the system it will continue killing flatworms.


 Why are Carbon Reactors slow to respond to emergencies?
In an emergency, we want to clean the water as fast as possible. It may not be possible or even practical to do a 50-100% water change.
Tank water flows through a typical Reactor very slowly, usually less than 200 gph. In a healthy aquarium, toxins are produced slowly. The slow water flow through a Reactor works fine for removing these toxins, but, when there is a sudden huge increase in toxic chemicals, especially the sudden death of thousands of Flatworms, the Reactor does not clean the water fast enough. That's when the answer given above is the best help.
